' warEBrnooE Jom'r BETWEEN TANKS AND EXTERNAL ASSOCIATED OBJECTS.

Application filed Januar y 31, 1923. .Serial No. 616,110.

To all whom/it may concern:

Be it known that 1, CHARLES W. R. E1011 HOFF, 'a citizen of the UnitedStates, and a resident of Oak Park, Cook County, Illinois,

have invented certain new and useful Improvements in Waterproof JointsBetween Tanks and External Associated Objects, of Which the following isdeclared to be a full, clear, and exact description.

This invention relates to water proof joints between tanks and externalassociated objects, such as pump bodies, covers, lids and so forth, andits principal object is to provide a simple,'efiicient and easilyassembled joint between an exterior element and voir, which shallbeiproof against the entrance of rain, snow or water and so forth.

Another object is to provide a joint inwhioh bolt, risret, or screwholes are dlspensed with, danger of leakage at such places is who lyeliminated. .The invention consists in the several novel featureshereinafter set forth and claimed.

The invention is clearly illustrated in the accompanying drawing, inwhich:

Fig. 1 is a plan, partly broken away, .of a pum base and tank top,illustrating one embodiment of the present invention; Fig. 2 is avertical, longitudinal section taken on line 2-2 of Fig. 1; Fig 3 -is avertical, cross section taken on the line 33 of. Fig. 1; and Fig. 4 is acentral, vertical section showing the application of the invention to acover.

Referring to said drawing and first to F i s. 1 to 3 inclusive, whichillustrate one em odiment of the invention, the reference character 5designates the top of a tank or reservoir such as is commonly used tocontain oil or othercliquids, and 6 designates an external member, hereshown as comprising the base of'a pump, which is mounted on the tank andus d for withdrawing the contents thereof; Said base is formed with theusual chamber 7 which opens downwardly into the oil u wardly into thedischarge opening from which leads the pump standard 9. The constructionof the pum is immaterial to this invention and no urther description ofits construction is necessary so far as this specification is concerned.

The top 5 of the tank is formed with an opening 10 for the receptlon ofthe pump 14 are employe ump cylinder 8, andformed with a downwardlyturned mar ginal flange 13 which fits over and around the upstandingflange of thetank, and rests on the tank. The flanges 11, 13 arecomparatively high and because of the overlapping feature, theyefi'ectively prevent rain, snow, sleet and the like from entering thetank through the opening 10.

The tank-and base are secured together against disconnection by the spotwelding process if desired, to make the connection permanent, or theymay berigidlgy secured together by clam bars 14 and means for clampingthe tan top and pump base together. As a preference, two clamp bars onelocated adjacent each end of the base, and extending transverselythereof. Each clamp bar has a central boss 16 and two arms 17 thatextend from the boss to the underside of the joint between the tank andbear a ainst the underside of the tank top. .The ase is formed on itsunderside with two bosses 18 which are tapped to receive screws 15 whichextend through the bosses 16 of the clamp bars. The arms 17 of saidclamp bars incline upwardly from the bosses and some s ace is leftbetween the bosses 16, 18 where y the ends of the clamp bars may pressthe tank to against the underside of the base flange wlien the screws 15are screwed up tight. Usually, a filler hole, covered by a cover, islocated in the tank top, which hole permits access to the screws in theassembling the base with the tank.

In the form of the invention illustrated in Fig. 4, a cover or lid 19 isshown, which covers an opening 10 in the top 5 of a tank. The cover hasa down turned flange 13 which surrounds the up turned flange 11 .of thetank. The cover is hinged on a the passage of the drippings and isformed with a gauge supporting lug 26 in which may be placed the usualgauge stick.

More or less variation of the exact details of construction is possiblewithout departing from the spirit of this invention; 1 desire,therefore, not to limit myself to the exact form of the constructionshown and described, but intend, in the following claims, to point outall of th invention disclosed herein.

I claim as new, and desire to secure by Letters Patent:

1. A water proof joint between atank and an associated external member,comprising a tank top having an opening therein, and a flange bentupwardly around said opening, an associated external member having anoutlet and formed with a marginal down turned flange overlapping said upturned flange and resting upon the outer face of the tank top,and clampbars secured meaaee member, whereby the top and bottom faces of thesheet metal tank top are clamped between said down-turned flange of theexternal member and the clamp bars.

2. A water proof joint between a tank and a pump base, comprising asheet metal tank top having an opening therein and a flange bentupwardly around said opening, a pump base having a down turned flangeoverlapping said up turned flange and resting upon the outer face of thetank top, and clamp bars secured to the underside of the pump base andbearing against the under side of the tank top directly under the flangeof said pump base, whereby the top and bottom faces of the sheet metaltank top are clamped between said down-turned flange of the pump baseand the clamp bars.

CHARLES W. R. EICHHOFF.
